Customer Reviews Smartwool Merino 250 Base Layer Crew

I volunteer for the National Park Service. I wear this under my uniform shirt. It is the perfect way to add warmth if needed and remain cool on those hotter days

Very pretty and well made leggings quality wise but very tight on me, I like compression leggings but these felt like they were squeezing the blood out of me and I’m small, only 5’2 and 115 lbs. I usually wear XS/S but the small where so tight I could barely put them on… very disappointed, I returned them.

Love the fabric & colors. Perfect for cold winter days when you don't want a lot of bulk or like to layer. Only reason for 4 starts is it runs a little small.

Fabulous warmth without weight! Wash beautifully. Perfect for skiing and hiking, but also lounging at home.

This is my go to under garment for cold weather. It keeps me toasty even on those really cold days. Smart wool makes the best wool products I have ever purchased.

I am traveling by train and found the weight/warmth to be perfect. It packs well, wears well for multiple days and it look great.

wow - do I LOVE this shirt! It's the perfect warm layer that can be worn alone or under another layer. I will be purchasing multiples! I bought an XL for some looseness - the "appropriate" size would have been skin tight.

I've been wearing these for years and years. The recent redesign is stellar - SO glad the arms became longer! Thank you for this change! The new side-seam design is very flattering. I live in these shirts - they are my daily morale boost. But please PLEASE bring back the Pewter Blue color! And also make Pewter Blue in the all-season weight... that is the best blue I've seen offered here the entire time I've worn Smartwool. And more classic rich alpine and royal blues as well :) It's nice to have options between super-light and super-dark and super-bright.

Beautiful, soft and quality base layer. The pattern is pretty to wear out and about also. I love this crew. It fits perfectly. I got XL because I want to wear this out and also hiking. It has nice sleeve length and shirt length and it's flattering.

Love these Smartwool crew tops and I own a little collection of them in various colors. Have noticed some colors are softer than others. They loosen up a little after some wears. Fit is athletic fit. I'm a size 10 and can wear a medium or a large. Or both for layering!!!

My go to winter top. Purchased in many colors and patterns. Feels great in colder weather and works with layers and vests.

SMARTWOOL is THE ONLY base I use for layering when hiking, traveling or even everyday. They are by far our favorite go to's. I only wish the precious blue was back. This is harder to match up to my other layers, but I love the fit and style.

I love these shirts! I bought a few or them for a trip and have been wearing them all the time at home! They are comfortable and keep the temperature comfortable

Love these shirts. I usually only buy one every 4 years b/c they last so long and wear so well.

I was worried when I purchased this amazing top. I'm 75 years old, small boned, 5'1" 105 lbs. and was concerned that it would not be appropriate for someone my age. Not at all it fits perfectly and I will buy more.

Perfect fit and a great warm layer for all day activity. This is my second one of these tops. Worth every penny!

I got the purple one with flowers! Love it. So soft and warm. Usually wear small but it was snug and I prefer a little moving room when hiking. So I got a med. much better

Very comfortable and soft. I wear it as a base layer and also as a solo shirt. Looks super cute with black pants or skort.

I got the blue one (it was on sale) and it keeps me warm but it holds stains kind of easily. I tried to spot wash but no luck. I'm about to wash it for the first time and I'm hoping it comes out. The fit is ok - but not quite the same cut as the classic thermal merino base layer 1/4 zip. The crew seems to be cut a bit larger.

The medium size feels smaller than the same type of top from 5+ years ago. The older top feels more comfortable. Has the sizing/ design changed?

I recently purchased the pecan color top. I love it! I have been buying Smartwool sweaters for years. I have one that is about 10 years old and it still looks like new! They are soft, warm, and comfortable. They hold their shape and color. The sleeve length and body length are perfect. The shape is flattering. What else can I say! For reference I am 5'6" and 127lbs.

I have two other shirt like this in other colors. I was really excited to purchase this one as the pattern was so different from my other two shirts and it is very lovely. The shirt was not the same. Tight and clingy. So, I ordered the next size (M) and decided that I would just hem the sleeves and the length if necessary. And, yes, they are so very long. Very long! And yet, the body of the shirt is not that much less clingy than the Small. Sigh! I will just hem the thing, but it bothers me when I consider the price and now the time that will be involved. Plus. I don't have a serger, so it won't be as nice of a hem. Thus the 4Star not 5.
